A method of manufacturing a security document is disclosed, comprising:(a) providing a polymeric substrate having first and second surfaces;then performing the following steps (b), (c) and (d) in any order:(b) applying a curable material to a first region of the substrate on its first surface;(c) forming the curable material such that its surface distal from the substrate follows the contours of an optically variable effect generating relief structure and curing the curable material such that the relief structure is retained by the cured material; (d) applying one or more coating layers to the first and/or second surface(s) of the substrate to define a viewing region, the coating layer(s) being absent at least on the first surface across all or part of the first region;then:(e) applying a masking substance to the first surface of the substrate, excluding at least a second region which includes at least part of the first region, the overlapping portions of the first and second regions defining a third region; (f) depositing a reflection enhancing material onto the first surface of the substrate such that, in the third region, the reflection enhancing material is deposited onto the cured material and follows the contours of the relief structure;wherein the masking substance impedes the retention of the reflection enhancing material such that the reflection enhancing material is retained only in areas to which the masking substance was not applied. |
